常用示例
Concatenate bitcode files
llvm-cat -o [output.bc] [file1.bc] [file2.bc]
Concatenate multiple bitcode files
llvm-cat -o [combined.bc] [*.bc]
Produce a module containing embedded modules
llvm-cat -b -o [bundle.bc] [file1.bc] [file2.bc]
说明
llvm-cat concatenates LLVM bitcode files. By default it produces a single bitcode module that contains the linked contents of all inputs. With -b, it produces a bundle in which each input remains a distinct embedded module, useful for tools that operate on multiple modules without merging them. It is part of the LLVM toolchain and is typically used in build systems that need to aggregate bitcode prior to linking, optimization, or analysis with llvm-link, opt, or llc.
参数
- -o _file_
- Write output bitcode to _file_ (defaults to standard output).
- -b
- Produce a binary bundle. Embeds each input module as a separate module inside the output, instead of linking them together.
- --help
- Display help information.

How do I run a basic llvm-cat example?
Run `llvm-cat -o [output.bc] [file1.bc] [file2.bc]` in a terminal, then adjust file names, paths, flags, or remote targets for your system.
What does -o _file_ do in llvm-cat?
Write output bitcode to _file_ (defaults to standard output).
